The trick itself is good and the tutorial goes well in-depth into the entire process. You get a lot
and the information is worth the money.
That being said, the material you get is low
quality. The cubes I got barely cuts corners and are worse than my $5 cube I bought from china 5
years ago. The sides one of my cubes also keep randomly falling off when turning. The other cube has
odd dark discolouring on the stickers. I'm not satisfied with the quality, however, you will not
easily find another cube like these, so you just have to get lucky when you buy this product.
Doing the one handed solves that Henry does is extremely hard with the cubes I have received
with this purchase (due to lack of corner cutting). For that, I have removed 2 stars, as only one
phase of this trick is usable and, in worst case, you may need to gimmick your own cubes.
